The ventilation pipe is the role of the accelerating air circulation and help the indoor air circulation, reduce the concentration of harmful gas is a kind of basic facilities and greenhouse gases, has certain fire performance, the performance of the protection in the transport of harmful gases。
Spiral type ventilation pipe as a new type of wind pipe construction technology, its advantage is self-evident, beautiful appearance, high strength, high degree of automation, mechanical processing speed and can reduce device workload, greatly improve the efficiency of the task.
High quality appearance. The inner wall of the air pipe is lubricated and the outer wall is fluent; the air duct is strong in intensity. Because of the average dispersion of the spiral ribs of the screw formed by the outer wall, the strength of the reinforcing bar is stronger than that of the popular bite type wind pipe;
The wind pipe sealing function is superior。 Due to mechanical processing, the utility model can reduce the remuneration, operate the mistake, ensure the tight air pipe, and the air leakage is much smaller than the current standard rule value; the data consumption is reduced。
Because the spiral wind pipe unit strength is greater than the popular wind, the wind pipe specifications with similar membrane thickness can be reduced to a model, and the wind pipe is longer than the popular bite type wind pipe, the same length of the wind pipe port number clear cut。

We would like to serve the eight guests with the best sense of service, and sincerely cooperate with friends from all walks of life at home and abroad for a better future。 Welcome to visit and negotiate!
